Development and clinical implementation of an MRI-only planning workflow featuring deep learning-based synthetic CT for prostate cancer external beam radiotherapy
Purpose (extract): “To clinically implement an MRI-only planning (MROP) workflow for both X-ray and MRI-guided systems.” Methods (extract): “MROP implementation involved optimizing MRI simulation protocols developing a deep learning-based sCT generation method, and automating fiducial marker detection. A multichannel CycleGAN model was trained using T1-weighted Dixon images to generate sCT. For SBRT cases, the immobilization device […]
Online correction of intrafraction motion during volumetric modulated arc therapy for prostate radiotherapy using fiducial-based kV imaging: A cohort study quantifying the frequency of shifts and analysis of men at highest risk
“Online correction of intrafraction motion during volumetric modulated arc therapy for prostate radiotherapy using fiducial-based kV imaging: A cohort study quantifying the frequency of shifts and analysis of men at highest risk” Background (extract): We sought to characterize setup corrections in our practice informed by the TrueBeam Advanced imaging package, and analyze factors associated with […]
Real-time gated proton therapy with a reduced source to imager distance: Commissioning and quality assurance
“Real-time gated proton therapy with a reduced source to imager distance: Commissioning and quality assurance” Introduction (extract): Real-time gated proton therapy (RGPT) is a motion management technique unique to the Hitachi particle therapy system. It uses pulsed fluoroscopy to track an implanted fiducial marker. The marker positional tolerance can be defined such that the proton […]
Article from Radiological Physics and Technology, 2024Inter-fractional error and intra-fractional motion of prostate and dosimetry comparisons of patient position registrations with versus without fiducial markers during treatment with carbon-ion radiotherapyArticle from Radiological Physics and Technology, 2024
“Inter-fractional error and intra-fractional motion of prostate and dosimetry comparisons of patient position registrations with versus without fiducial markers during treatment with carbon-ion radiotherapy” Abstract (extract): In 2020, data from 15 patients with prostate cancer who received carbon-ion beam radiotherapy (CIRT) with gold markers were investigated. We checked marker positions before and during irradiation to […]
Real-time tumor-tracking radiotherapy with SyncTraX for primary liver tumors requiring isocenter shift
“Real-time tumor-tracking radiotherapy with SyncTraX for primary liver tumors requiring isocenter shift” Abstract (extract): The SyncTraX series enables real-time tumor-tracking radiotherapy through the real-time recognition of a fiducial marker using fluoroscopic images. In this system, the isocenter should be located within approximately 5–7.5 cm from the marker, depending on the version, owing to the limited […]
Fiducial markers in adjuvant setting for a patient affected by endometrial cancer: a case report
“Fiducial markers in adjuvant setting for a patient affected by endometrial cancer: a case report” Introduction (extract): Implantation of Fiducial Markers (FMs) in the vaginal cuff of patients receiving radiotherapy (RT) or brachytherapy could help patient daily setup, image guidance and intra-fraction detection of the radiation targets. Clinical case (extract): Case report of a woman […]
